Although I am pleased with the overall performance of the Palit 9800GTX+, I was slightly disappointed by its overclockability. Although, the Palit 9800GTX+ has decent clocks to begin with but I really expected more. Its core clock, memory clock and shader clock could only be increase by 84MHz, 72MHz and 162MHz, respectively. This marginal increase in clocks is a lot lower than another 9800GTX+ reviewed by OCC. The 9800GTX+ clocks in this review were adjusted using Rivatuner 2.11 and temperatures were monitored by GPU-Z 0.2.8. To reach my final overclock, I bumped up the GPU and memory in 25MHz increments and tested stability using 3DMark06. The GPU core clock and shader clock were linked until I hit instability above 1998MHz on the shader. I then unlinked the two and was able to get the GPU up to 824MHz. The stock cooling solution did a fantastic job of controlling temperatures at clock settings. I never saw the GPU core rise above the upper 60s at load, which is 20-30 degrees cooler than the 9800GTX+'s direct competition, the 4850.
